Straight die grinder for precision work
The Chicago Pneumatic CP872 is a straight die grinder built for deburring, porting and finishing tasks in metalworking and automotive shops. Its aluminium body and ball-bearing construction keep vibration low during extended use. A lever throttle provides variable speed control from zero to 22,000 rpm. The tool accepts both 1/4 in. and 6 mm collets for a range of carbide burs and mounted stones.
Suited for detail grinding, not cut-off
Technicians who need a lightweight straight grinder for tight corners and intricate profiles will find the 0.4 HP output and rear exhaust convenient. The 6.5 CFM average consumption suits smaller shop compressors. Buyers who need a cut-off tool or a right-angle head for confined spaces should look at a different style, as this model is not rated for cut-off wheels and has a fixed straight body.
90 psi operating pressure requirement
The grinder requires a steady 90 psi supply through a 1/4 in. NPT inlet with a minimum 3/8 in. hose to deliver its rated 26 CFM at full load. If the airline cannot maintain that pressure and flow, speed and torque will drop below the specified 22,000 rpm free speed. Verify compressor capacity before purchase.

Questions about this item
Does the CP872 come with both collets or do I need to buy the 6 mm size separately?
The grinder includes both the 1/4 in. and 6 mm collets in the box, so no separate purchase is needed for either size.
Should I choose the 1/4 in. or 6 mm collet for my carbide burs?
Use the collet that matches the shank of your accessory — 1/4 in. for imperial shanks and 6 mm for metric shanks; both collets are supplied with the CP872.
What does the 22 000 rpm free speed mean when I am grinding under load?
At 90 psi the tool runs at 22 000 rpm unloaded; under full load it draws 26.0 CFM and speed drops, so size your compressor to deliver 26 CFM at 90 psi for consistent performance.
